Background: To better understand symptoms experienced by patients infected with chronic hepatitis C virus (HCV), valid and reliable patient-reported outcome (PRO) measures are needed.
Aim: To assess the reliability and validity of 10 patient-reported outcomes measurement information system (PROMIS) measures and the Headache Impact Test-6 (HIT-6) in a large national sample of patients with HCV.
Methods: Pre-treatment data from 961 patients with HCV starting direct acting antiviral therapy at 11 U.S. liver centers were analyzed. Internal reliability was evaluated using Cronbach's alpha coefficient; frequency distributions were examined for floor and ceiling effects; structural validity was investigated via item-response-theory models; convergent validity was evaluated using correlations with theoretically-similar items from the HCV-PRO and memorial symptom assessment scale (MSAS); and known-groups validity was investigated by observing PRO differences by liver disease status and number of comorbidities.
Results: The HIT-6 and the majority of the PROMIS measures yielded excellent reliability (alphas ≥ 0.87). Ceiling effects were infrequent ( < 4%), while 30%-59% of patients reported no symptoms (floor effects). The data supported structural validity of the HIT-6 and most PROMIS measures. The PROMIS measures showed moderate to strong correlations with theoretically-similar items from the HCV-PRO and MSAS (0.39-0.77). Trends were observed between worse PRO scores and advanced cirrhosis and greater number of comorbidities, lending support for known-groups validity.
Conclusions: The psychometric properties of the HIT-6 and PROMIS measures performed satisfactorily in this large cohort of patients with HCV starting direct acting antiviral therapy. Opportunities exist for further refinement of these PROs. Evaluation of performance over time and in under-represented subgroups is needed.

Background: Gastrointestinal ultrasound (GIUS) is recommended for monitoring Crohn's disease (CD). GIUS scores are used to quantify CD activity. Among them, IBUS-SAS (International Bowel Ultrasound Segmental Activity Score), BUSS (Bowel Ultrasound Score), Simple-US (Simple Ultrasound Score), and SUS-CD (Simple Ultrasound Score for Crohn's Disease) are most commonly used.

Background: The Society of Cardiovascular Angiography and Intervention (SCAI) has defined 5 stages of cardiogenic shock (CS). In patients with acute myocardial infarction (AMI) who initially present in stable hemodynamic condition (SCAI CS stage: A or B), CS stages could deteriorate despite therapeutic management. However, deterioration of SCAI CS stages after AMI remains to be fully characterized.

Background: The role of lipoprotein(a) (Lp(a)) in the risk-assessment of patients with de-novo stable chest pain is sparsely investigated. We assessed the association between Lp(a) concentration and the presence of coronary stenosis on coronary computed tomography (CT) angiography in a broad population of patients referred with stable chest pain.
Methods: Lp(a) measurements and coronary CT angiography were performed in 4,346 patients with stable chest pain and no previous history of coronary artery disease.

Background: American College of Surgeons (ACS) trauma center verification has demonstrated improved outcomes at individual centers, but its impact on statewide Trauma Quality Improvement Program (TQIP) Collaboratives is unknown. A statewide TQIP Collaborative, founded in 2011, noted underperformance in six of eight patient cohorts identified in the TQIP Collaborative report. We hypothesized that requiring ACS verification for level I and II trauma centers would result in improved outcomes for the state collaborative.
